TINY particles of dust pose a more serious risk to satellites than huge lumps
of space junk, according to a team of British scientists who have analysed
damage to solar panels from the Hubble Space Telescope.
Most bits of space junk, even pieces as small as a few centimetres across,
are tracked by the US Air Force. This allows any spacecraft that is on a
collision course to be moved out of the way. But some particles are too small to
be tracked by radar.
This week scientists from the Open University and Oxford Brookes University
will tell the Hypervelocity…
